Highly heat-resistant, silicone-sheathed flexible cable with overall copper braided screening

Applications

Silicone-insulated cables with copper braided screening are used when exposure to high temperatures and temperature variations would cause conventional PVR-insulated cables to become brittle. These cables are preferably used in the metal-lurgical industry, steel works, hot-rolling mills, coking plants, coking plants, foundries, cement works,glass factories and ceramics plants as well as in the production of electric motors, in ships and aeroplanes, in heating equipment, and in lighting gear etc.

The insulation consists of silicone rubber. It is resistant to vegetable and animal fat, many types of oil and diluted acids. no decomposition occurs when exposed to alcohol, plasticizers, alkaline solutions, saline solutions etc.

Should the calbe burn, an insulating silicon dioxide layer will remain on the conductor to render it short circuit proof.

The high screening density provides interference-free pulse and signal transmission.
